Detailed tire and wheel breakdown for the 1994 Caterham Seven
Tire geometry — 185/60R14
The 185/60R14 fitted to the 1994 Caterham Seven has a section width of 185mm and an aspect ratio of 60%, mounted on a 14-inch rim. That gives a sidewall height of 111.0mm (4.37") and an overall outside diameter of 577.6mm (22.74"). At highway speed this tire completes roughly 551 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 1994 Caterham Seven while keeping the speedometer accurate, target a 195/50R15 (plus-one). For a softer ride or winter setup, a 175/71R13 (minus-one) keeps the overall diameter within ±3% of stock, which is the industry tolerance for ABS and stability control to stay calibrated.
Wheel fitment specs
The 1994 Caterham Seven uses a 4x108 bolt pattern with a 63.4mm hub bore. Safe rim width range for the OEM tire is 5.5J – 6.5J, and offsets in the ET19 – ET29 window will clear suspension and fender without rubbing on most setups.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 1994 Caterham Seven is printed on the driver-side door jamb sticker — always defer to that value, not to the maximum pressure printed on the tire sidewall. Check pressure monthly and before long trips; under-inflation by 20% can reduce tread life by 25%.
